Well, as far as I'm concerned, those Tesselatas are one of the meanest eels to be found. They don't like just about anything and have one nasty attitude. They also need a larger tank than snowflakes and chainlinks. I personally have a snowflake eel. They are very cool, hardy, and interesting to watch. He takes all foods I give him. He eats small, meaty foods such as: krill, brine shrimp, mussel, squid, and silversides. Feed them a varied diet to keep them healthy. They don't need as large of a tank as Tesselatas do. They can go in tank of 45 gallons or more. Some people even have them in smaller tanks with no problems although, I recommend a 45 gallon or more. Chainlinks are basically the same as snowflakes only the color difference. They eat the same foods and require the other forms of basic are needed to keep a snowflake healthy. They both are very hardy which is a plus and they are relatively easy to care for and they are, compared to most eels, docile. Of course this doesn't mean that they are really nice as they will still eat inverts and small fish. I would recommend that you avoid the Tesselata unless you want a big tank with a couple really mean fish in it.
